A considerable variation exists in the orientation of the hearts of different subjects. These variations make the interpretations of electrocardiograms substantially more difficult. They can be eliminated by a transformation of the "coordinates" of the three components of the heart's dipole moment to a new frame of reference which is rotated with respect to the original one. An electronic instrument for accomplishing this end is described in this article.
